Katarina vs Sivir Counter Pick
Matchup Summary
What the Data Means
Spell Shield decides most of these fights. Sivir blocks a single enemy ability with her E and is rewarded with health and a burst of movement speed, so an opening Bouncing Blade or a committed Shunpo can be erased by one well-timed click. The record still favours the assassin: 60.5% from 152 games recorded on patch 16.13.1. What tips it is the interval after the barrier expires. Katarina pays no resource cost at all, so she can bait the shield with a cheap dagger and return seconds later, while Boomerang Blade and Ricochet both drain a mana pool that empties fast under sustained pressure.
Sivir is the sturdier champion only on paper. She carries 30 armor at level one and 98 at level 18, against Katarina‘s 32 and 111.9, and finishes 140 health lower at 2,368. Her damage is physical, which armour answers; Katarina’s is magic, which pushes Sivir toward magic resist she rarely buys early. Both run 335 base move speed, and Fleet of Foot only accelerates her after she lands an attack on a champion, making it reactive rather than preventative. On The Hunt hands the whole team move speed and shortens her cooldowns, which matters in grouped fights and much less when Voracity refunds Katarina’s cooldowns off a single kill.
